'LINE-CASTING MACHINE Specification o Letters Patent.

' Application filed December 14, 1908.

Patented June 22,1909.

Serial No. 467,434.

My invention hasreference more particul.larly to Mergenthalerline-casting machines,

wherein the'slugs or linotypes are cast in a slotted y mold mounted in avertical disk which is given an intermitt'ing rotation.-`

y i The primary objectof the invention is to rovide for instantaneouschange 'in the ength of the mold slot ,andl of the slugs producedthereimand at the same time to give the mold proper. support andguidance, so that it may noti be Vsprun facewise out ofposition vby theaction.V o `the .usual slug trimming knife or the ejector at the rear.To this ,end I provide a mold having in one end a sliding liner fto`control the length ofthe slot. This liner, lseated lbetween the 4 cag-`and body of the mold, is preferably provide with teeth, to be engaged byteeth on a Wrench or pinion for eecting the longitudinal adjustment. Theliner is also connected tothe top and bottom members of the mold bylongitudinal tongues and grooves, whereby the twol parte ofthe mold arekept in line facewise without the em loyment ofl the usual connectingposts at t e ends,

' v Thetwo parts of the mold are connectedand drawn together upon thesliding liner by a screwseated in the mold outside of the disk, so thatthe latter is relieved from the 4strain to which it is subjected whenthe cony'filling screw is threaded into the disk.

.Instead of using 1n connection with't'he disk a stationary frontsupport againstjvhich it bears to prevent it from s ringing forward asthe slug is carried with t e mold past thev .rear trimmin knife, I nowprovidethe disk with an annu ar flange or groove adapted to be engagedbya rear supporting arm, so that there is vno interference with themold-tightening'- screw above referred to. This arrangement leaves theentire face of the mold diskand mold exposed-or uncovered, so that therejecting end vof the mold liner and the mold) tightening screws willmeet with no obstruction as the wheel revolves.

With the exception of the parts specificwrench or proved mold therein.Fig; l3 isa top lan view of the mold. disk and one-end O the mold. Fig.4 is a perspective view of aportion of the mold disk and one end of themold with the sliding liner therein. Fig. 5 is a perspective view ofthesliding liner.

Figs. 7 and 8 are similar sections showing alternative or equivalentforms of the rear support or guide for the mold disk. Fig. 9 is aperspective -view of the removable ey for o erating the linerclampingE-Lscrew and for a justing the liner. eferring to the drawings,A. re )resents the mold, B the vertical disk on w 'ch'the moldispermanently secured, C the slide mounted tornove horizontally in themain frame,and 4provided With alaterally extending arm c which receivesand sup Orts the hub or journal b of the rnolddis B, thearrangement'being such that thedisk may rotate about its axis' and alsobe carried for- Ward and backward by the movement of the slide in orderto carry the face of the mold, A, to and from the line ofmatrices withwhich it coperates, the general action of these parts beingth'e same asin existing machines; The disk B is constructed as usual with an annularperi heral flange, b', extending rear- 'rotation of the disk and mold.This front 6 is a section on the line 6-6 of Fig. 2.

support would stand in the path of the imi i proved parts hereinafterdescribed, and lI therefore dispense with thesarne and provide I `thedisk on the rear side with a ring of steell or other suitablematerial-fb?, secured 'to its rear face and extending inward beyond theflange b', so that it mayv engage the outer end of the arm c formed onthe mold slide for the purpose, as shown in Fig. l. Thisrigid arm,caring closely. against the front face ofthe ring, '63, serves as aneffectual support to prevent the disk froin f )ringing forward. Thering, b3, may be cast integral withl the wheel, but 'as an apdplied ringmay be made of harder material an of greater strength than the cast irondisk, its use is preferred,

`Instead of having the ring b3 extend inward beyond the annular iiange b.the latter may be widened and formed with agroove, b4, to receive theouter end of the arm c as shown in Fig. 7 or the flange may -be formedin the manner shown in Fig. 8, in which the flange ofthe disk isextended rearwardly, grooved in the outer side, and adapted to receivethe supporting arm. In short, the only requirementis that the disk shallhave at the rear side an annular surface to engage a rigid arm or guide.

I believe it to be wholly new to support a mold disk against forwardmovement by a support at the rear, and this I claim broadly in any fornithe equivalent of that herein shown. l

Passing now to the construction of the mold A, a. representsthe bodyportion secured rigidly to the mold disk, u the cap portion overlyingthe body and separated therefrom by the x'ed intermediate liner, (t2,and the sliding liner (t3.

The cap is held down in place to confine the liners in position by twoscrews D and E. By loosening these screws the cap may be released topermit the longitudinal inovement of the liner c3, or the removal .ofboth liners when others of different thickness are to be introduced forthe purpose of changing the vertical height .of the slot and thethickness of the slugs produced therein.

The screw E has its lower end reduced or necked down, leav-iiig ashoulder to bear on top of the cap,- through which it passes loosely,while the lower extremity is threaded into the body portion. The screwpasses through a longitudinal slot, as in the liner a3'.

lhen this screw is tightened the cap and body portion are drawn togetherupon the intermediate liners without subjecting the rim or flange of thedisk to strain. In this class of device as heretofore constructed it wasthe common practice to thread the ca the mold slot is varied isv,provided onl the upper and lower sides with longitudinal grooves, a5and ci, to receive corresponding ribs formed on the cap and body'nearthe outer end. v'Ihis construction serves to guide the" liner accuratelyand also to hold the faces of the cap, liner and body in linevertically, in other words, to keepthem' Hush" at the front and rear. Ifdesired the tongues or ribs may be formed on the liner, and the 'groovesformed in the apiand body'.- Inl either construction the tonguesand'grooves take the place of the vertical posts or guides them line`The longitudinall adjustment of the liner may be effected in vanyconvenient manner. I prefer, however', to provide'it along one connectthe cap and body portion and keep 4edge with transverse teeth, ai', andto adjust commonly employed in this class of molds to Then extremeadjustment of the mold slot is required lthe liner will be of suchlength that'its o uter end would encounter the flange of the disk. Toavoid this the disk is provided with a slot, b5, through which the endof the liner `may be projected, as shown in Figs. 2 and 4. The fact4that theseiparts project beyond the forward face .of the disk isimmaterial in view of the fact that the disk supports are transferredfrom the front to the rear as already explained. Because of thistransfer there exists in front of the disk a free or unopposed paththrough which the mold, liner, and mold adjusting screws may pass.

Change in themeasure or length of the line may be effected by releasingthe screw E, moving the liner a3 to the required position, andthereafter tightening the screw. If change in the thickness of the slugproduced is demanded both the screws, I) and E, are loosened to` permitthe removal' of the liner c2, which is of the `common form, in allodgewise direction 5 the screw E is removed in order to permit theremoval of the liner a3 in an eiidwise direction; and the two liners arereplaced by others ofvgreater or less thickness as required.-

Having described my invention, what I claim and desire to secure byLetters Patent, is: i

1. In a machine of the class described, thc mold disk having an annularsurface, in combination with a rear support engaging said the annularflange t3 and the disk sustainingy f slide having the arm c engaged withthe flange. y 3. The mold carrying disk for aline castingmaohine havingan annular iiange or 5 ring 7f3 substantially as described.v

4. The mold carrying disk for a line easting. machine having an annularflange lb3 secured to its rear side.

5. In combination With the disk having an annular iiange and the moldbody fastened thereto, the mold cap, the slotted slidinglinervconneotedto the cap and the body by y longitudinal ribs and grooves, and theoonfming screw bearing on the cap and threaded 15 into the body, and the'disk support engaging l the iiange from the rear; whereby a clean pathis afforded for the travel ofthe screw as the disk is rotated.

6. In combination, the mold disk andthe mold cap and body, theintermediate liner connected thereto by longitudinal tongues` 4andgrooves, and the confining srew, ex-

tended beyond the disk.
